C1.3.19: Explain the link between the light-dependent and light-independent reactions and how the light-independent reactions cannot continue in the absence of light.

This bundle contains 35 comprehensive checklist for the Cambridge iGCSE Co-ordinated science syllabus. Updates have been made to B9 and C12&13 have been made (initally incorrect checklist were uploaded Each checklist contains a detailed breakdown of the content students are expected to know. The checklist use a RAG system (Red, Amber, Green) which students use to evaluate their understanding: Red: Students is not familiar with the objective and need to revise Amber: Student is somewhat familiar with the objective but still need to revise Green: Student is confident with the objective. These checklist are fantastic for supporting students with their revision for either end of year exams, end of topic revision or for their actual iGCSE.
